His breakthrough came in 1962 where he won 2 silver medals at the world championship in Italy, Individual & 100 km team time trial.

He won the individual time trial in the Giro d'Italia in front of Rudi Altig, Eddy Merckx and Jacques Anquetil.

Ritter rode the Giro d'Italia nine times, and is the Danish rider with the best GC finish (seventh, in 1973) and the most stage wins (three).

The heartbreak of the mountain stages, the intensity of the time trial (known as "the race of truth"), quiet moments on the road and the mundane daily signing-in are all part of the film.

Ritter is featured in the time-trial segment, with his technical, physical and psychological preparations and later performance detailed to the accompaniment of a single, prolonged violin note.
